Signature method
Use an uploaded image, draw a signature, or type a signature name for live PDF preview.
Upload signature image is selected. Choose PNG/JPG for export or WebP for preview only.
Draw Signature canvas
Draw your signature here
No drawn signature yet. Draw inside the canvas to show it in the live PDF preview and enable export.
You can clear and redraw anytime. After an export is ready, changing the drawing or placement clears the old result so the next download is fresh.
